Will the real Michael Cera please stand up in Paper Hearts?

When Nick and Norah's Infinite Playlist came out this October, TheMovieBlog posted a short lamentation: "Already Bored With Michael Cera." They were neither the first, nor the last, to voice such opinion—film and TV critics had long been noting the stark similarities among the roles of his career—but they did state the concern with a certain amount of pith:

Yes, I get it Cera. You’re a mildly awkward, good hearted, understated
and sympathetic post-teen who struggles with identity and self
confidence despite having a lot to offer. Oh wait which one of his
characters are we talking about? Oh that’s right ALL OF THEM!!!

He's come a long way from acting as a sixth-grade alien—and his
reprisal of breakout role George Michael Bluth in the now-confirmedArrested Development movie will likely please just about everyone—but
the claim of sameness is something the Canadian-bred actor has had a hard time of escaping recently. And now there's something new to fan the flames of debate.

Cera has been quietly working on Paper Hearts, a Nicholas Jasenovec-directed film that's been described by sources close to its production as part
documentary, part scripted comedy focused on the relationship between
Cera and his actual girlfriend, Charlyne Yi (best known as the Asian
stoner-girl of Knocked Up). As with best-of achieving Juno and
indie-rock touting Nick and Norah, music plays a central role in the
film. Other Judd Apatow mainstays are also reported to be involved.

Until last week, Paper was mostly under the radar (its IMDb entry is more than a little
scant), with its helmsmen hoping
it could make a big surprise splash debuting at next year's Sundance. "It's pretty
much 'the one,'" said one seller, "at least as far as festival
programmers are concerned."

Perhaps Paper will answer some of our questions: Will Cera's most personal role
simply peel the George away from an Arrested forebear? Should we
expect another Paulie/Nick/Evan? Could this be a different Michael, like the one from
online comedy romp Clark and Michael?
Or will we have to pin our hopes on Cera's turn as Nick Twisp in Youth In Revolt for a new kind of leading man?
